Kernal in Brief

What About Kernal ??



Kernal Is The Important Part in any OS. used To Manage All resources of computer like I/O , Virtual Memory , Disk Management and More .

When We Speak As Layers Kernal is second layer before CPU, Memory , Devices Then Kernal Finally Application With Gui Or Not that isn’t the point :).

From Here About Types Of Operating systems

Some Special Systems don’t Need Kernal But All multitasking and multiple users
Most in need to kernal as principle part of its parts 
in order to manage processes , tasks , users , time and usage in general for all users or management tasks in multitasks os .

this important part need design in order to work correctly with no errors

there are 3 models of designs :
Monolithic kernels


In this model os merged in one part kernal not separated this make os faster but any error make all system fails like virus or malware in general .
Microkernels Kernals


not as one this divides os into parts but time for sending and receiving data is wasted . any part is standalone .

Hybrid kernels


merged design from
Microkernels and Monolithicto make system faster and working with high performance .


That as i can say a definition about kernal
